SAFETY WARNING CALIFORNIA PROPOSITION 65 WARNINGS The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. The Above For Gasoline Engines ARC WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING. Read and understand the following safety highlights. For additional safety information, it is strongly recommended that you purchase a copy of Safety in Welding & Cutting - ANSI Standard Z49.1 from the American Welding Society, P.O. Box , Miami, Florida or CSA Standard W A Free copy of Arc Welding Safety booklet E205 is available from the Lincoln Electric Company, St. Clair Avenue, Cleveland, Ohio BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS. 1.h. To avoid scalding, do not remove the radiator pressure cap when the engine is hot. ELECTRIC AND MAGNETIC FIELDS may be dangerous 2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines 2.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding. 2.c. Exposure to EMF fields in welding may have other health effects which are now not known. 2.d. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit: 2.d.1. Route the electrode and work cables together - Secure them with tape when possible. 2.d.2. Never coil the electrode lead around your body. 2.d.3. Do not place your body between the electrode and work cables. If the electrode cable is on your right side, the work cable should also be on your right side. i 1.g. To prevent accidentally starting gasoline engines while turning the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate. Mar 95 2.d.4. Connect the work cable to the workpiece as close as possible to the area being welded. 2.d.5. Do not work next to welding power source.

3 ii SAFETY ii ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically hot when the welder is on. Do not touch these hot parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. 3.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground. In addition to the normal safety precautions, if welding must be performed under electrically hazardous conditions (in damp locations or while wearing wet clothing; on metal structures such as floors, gratings or scaffolds; when in cramped positions such as sitting, kneeling or lying, if there is a high risk of unavoidable or accidental contact with the workpiece or ground) use the following equipment: Semiautomatic DC Constant Voltage (Wire) Welder. DC Manual (Stick) Welder. AC Welder with Reduced Voltage Control. 3.c. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or semiautomatic welding gun are also electrically hot. 3.d. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded. 3.e. Ground the work or metal to be welded to a good electrical (earth) ground. 3.f. Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation. 3.g. Never dip the electrode in water for cooling. 3.h. Never simultaneously touch electrically hot parts of electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders. 3.i. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock. 3.j. Also see Items 6.c. and 8. ARC RAYS can burn. 4.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards. 4.b. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays. 4.c. Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal. FUMES AND GASES can be dangerous. 5.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases.when welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone. When welding with electrodes which require special ventilation such as stainless or hard facing (see instructions on container or MSDS) or on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low as possible and below Threshold Limit Values (TLV) using local exhaust or mechanical ventilation. In confined spaces or in some circumstances, outdoors, a respirator may be required. Additional precautions are also required when welding on galvanized steel. 5.b. Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and other irritating products. 5.c. Shielding gases used for arc welding can displace air and cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe. 5.d. Read and understand the manufacturer s instructions for this equipment and the consumables to be used, including the material safety data sheet (MSDS) and follow your employer s safety practices. MSDS forms are available from your welding distributor or from the manufacturer. 5.e. Also see item 1.b. Mar 95

4 iii SAFETY iii WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available. 6.b. Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations. Refer to Safety in Welding and Cutting (ANSI Standard Z49.1) and the operating information for the equipment being used. 6.c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard. 6.d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even though they have been cleaned. For information, purchase Recommended Safe Practices for the Preparation for Welding and Cutting of Containers and Piping That Have Held Hazardous Substances, AWS F4.1 from the American Welding Society (see address above). 6.e. Vent hollow castings or containers before heating, cutting or welding. They may explode. 6.f. Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position or in confined places. Always wear safety glasses with side shields when in a welding area. 6.g. Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail. 6.h. Also see item 1.c. CYLINDER may explode if damaged. 7.a. Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition. 7.b. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support. 7.c. Cylinders should be located: Away from areas where they may be struck or subjected to physical damage. A safe distance from arc welding or cutting operations and any other source of heat, sparks, or flame. 7.d. Never allow the electrode, electrode holder or any other electrically hot parts to touch a cylinder. 7.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve. 7.f. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use. 7.g. Read and follow the instructions on compressed gas cylinders, associated equipment, and CGA publication P-l, Precautions for Safe Handling of Compressed Gases in Cylinders, available from the Compressed Gas Association 1235 Jefferson Davis Highway, Arlington, VA FOR ELECTRICALLY powered equipment. 8.a. Turn off input power using the disconnect switch at the fuse box before working on the equipment. 8.b.

Ground the equipment in accordance with the U.S. National Electrical Code and the manufacturer s recommendations. Mar 95

5 iv SAFETY iv PRÉCAUTIONS DE SÛRETÉ Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent dans ce manuel aussi bien que les précautions de sûreté générales suivantes: Sûreté Pour Soudage A L Arc 1. Protegez-vous contre la secousse électrique: a. Les circuits à l électrode et à la piéce sont sous tension quand la machine à souder est en marche. Eviter toujours tout contact entre les parties sous tension et la peau nue ou les vétements mouillés. Porter des gants secs et sans trous pour isoler les mains. b. Faire trés attention de bien s isoler de la masse quand on soude dans des endroits humides, ou sur un plancher metallique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grande partie du corps peut être en contact avec la masse. c. Maintenir le porte-électrode, la pince de masse, le câble de soudage et la machine à souder en bon et sûr état defonctionnement. d.ne jamais plonger le porte-électrode dans l eau pour le refroidir. e. Ne jamais toucher simultanément les parties sous tension des porte-électrodes connectés à deux machines à souder parce que la tension entre les deux pinces peut être le total de la tension à vide des deux machines. f. Si on utilise la machine à souder comme une source de courant pour soudage semi-automatique, ces precautions pour le porte-électrode s applicuent aussi au pistolet de soudage. 2. Dans le cas de travail au dessus du niveau du sol, se protéger contre les chutes dans le cas ou on recoit un choc. Ne jamais enrouler le câble-électrode autour de n importe quelle partie du corps. 3. Un coup d arc peut être plus sévère qu un coup de soliel, donc: 6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque d incendie dû aux étincelles. 7. Quand on ne soude pas, poser la pince à une endroit isolé de la masse. Un court-circuit accidental peut provoquer un échauffement et un risque d incendie. 8. S assurer que la masse est connectée le plus prés possible de la zone de travail qu il est pratique de le faire. Si on place la masse sur la charpente de la construction ou d autres endroits éloignés de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer des risques d incendie ou d echauffement des chaines et des câbles jusqu à ce qu ils se rompent. 9. Assurer une ventilation suffisante dans la zone de soudage. Ceci est particuliérement important pour le soudage de tôles galvanisées plombées, ou cadmiées ou tout autre métal qui produit des fumeés toxiques. 10. Ne pas souder en présence de vapeurs de chlore provenant d opérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de l arc peuvent réagir avec les vapeurs du solvant pour produire du phosgéne (gas fortement toxique) ou autres produits irritants. 11. Pour obtenir de plus amples renseignements sur la sûreté, voir le code Code for safety in welding and cutting CSA Standard W PRÉCAUTIONS DE SÛRETÉ POUR LES MACHINES À SOUDER À TRANSFORMATEUR ET À REDRESSEUR a. Utiliser un bon masque avec un verre filtrant approprié ainsi qu un verre blanc afin de se protéger les yeux du rayonnement de l arc et des projections quand on soude ou quand on regarde l arc. b. Porter des vêtements convenables afin de protéger la peau de soudeur et des aides contre le rayonnement de l arc. c. Protéger l autre personnel travaillant à proximité au soudage à l aide d écrans appropriés et non-inflammables. 4. Des gouttes de laitier en fusion sont émises de l arc de soudage. Se protéger avec des vêtements de protection libres de l huile, tels que les gants en cuir, chemise épaisse, pantalons sans revers, et chaussures montantes. 1. Relier à la terre le chassis du poste conformement au code de l électricité et aux recommendations du fabricant. Le dispositif de montage ou la piece à souder doit être branché à une bonne mise à la terre. 2. Autant que possible, I installation et l entretien du poste seront effectués par un électricien qualifié. 3. Avant de faires des travaux à l interieur de poste, la debrancher à l interrupteur à la boite de fusibles. 4. Garder tous les couvercles et dispositifs de sûreté à leur place. 5. Toujours porter des lunettes de sécurité dans la zone de soudage. Utiliser des lunettes avec écrans lateraux dans les zones où l on pique le laitier. Mar. 93

If the wing nut is positioned in line with the locking tab, the tab cannot be depressed to load or unload the wire spool. Make certain the start end of the wire, which may protrude through the side of the spool, does not contact any metallic case parts. FIGURE B.2 Wire Spool Spindle Locking Tab 8 Wire Spool 5 Be sure that this stud engages the hole in the wire spool. To wire drive Wire Spool must be pushed all the way on the spindle so that the spindle s tab will hold it in place. The Wire Spool must rotate clockwise when wire is dereeled.

17 B-4 OPERATION FIGURE B.4 B-4 Wire Spindle Shaft 4" Wire Spool 2 To wire drive FIGURE B.3 Friction Brake Adjustment Wing Nut and Spacer With wire spool installed on the spindle shaft and the wing nut loose, turn the spool by hand while slowly tightening the wing nut until a light drag is felt. Tighten the wing nut an additional 1/4 turn. Note: When properly adjusted, the brake should provide only enough drag to prevent overrun of the spool and excess slack in the wire. Too much drag may result in wire feeding problems, and may cause premature wear of wire drive system components The Wire Drive Feed Roll can accommodate two wire sizes by flipping the wire drive feed roll over. The sizes are stenciled on the drive roll. 6. The idle roll pressure adjustment wing nut is factory set to approximately five full turns from where the wing nut first engages the threads of the pressure arm (1). If feeding problems occur because the wire is flattened excessively, turn the pressure adjustment counter-clockwise to reduce distortion of the wire. Slightly less pressure may be required when using " (0,6 mm) wire. If the drive roll slips while feeding wire, the pressure should be increased until the wire feeds properly. 1 WARNING Wire Threading Refer to Figure B.4 1. Release the Spring Loaded Pressure Arm (1) rotate the Idle Roll Arm (2) away from the Wire Feed Drive Roll (3). Ensure that the visible, stenciled size on the drive roll matches the wire size being used. 2. Carefully detach the end of the wire from the spool. To prevent the spool from unwinding, do not release the wire until after step Cut the bent portion of wire off and straighten the first 4 (100 mm). 4. Thread the wire through the In-going guide tube (4), over the drive roll (3), and into the out-going guide tube (5). 5. Close the idle roll arm (2) and latch the spring loaded pressure arm (1) in place (now you may release the welding wire). When inching the welding wire, the drive rolls, the gun connector block and the gun contact tip are always energized relative to work and ground and remain energized several seconds after the gun trigger is released. 7. Refer to Figure B.5. Remove gas nozzle and contact tip from end of gun. 8. Turn the ON ( I ). 9. Straighten the gun cable assembly. 10. Depress the gun trigger switch and feed welding wire through the gun and cable. (Point gun away from yourself and others while feeding wire.) Release gun trigger after wire appears at end of gun. Note: If the wire will not feed smoothly, or if the wire feed motor shuts off unexpectedly, see the "FEEDING PROBLEMS" section of the "TROU- BLESHOOTING GUIDE" in this manual. 11. Replace contact tip and gas nozzle. 12. Refer to Figure B-6. Cut the wire off 3/8 1/2 (10 13 mm) from the end of the tip. The SP-135 PLUS is now ready to weld.

Refer to the ACCES- SORIES section for more information about selecting gas cylinders for use with the. 1. For CO 2, open the cylinder very slowly. For argonmixed gas, open cylinder valve slowly a fraction of a turn. When the cylinder pressure gauge pointer stops moving, open the valve fully. 2. If using a regulator with an adjustable flow meter, close the gun trigger and adjust the flow to give cubic ft per hour (CFH) (7 10 I/min) [use CFH (10 12 I/min) when welding out of position or in a drafty location for CO 2 ]. For argon mixed gas, trigger to release gas pressure, and turn off the adjust the flow to give CFH (12 14 I/min). 3. Keep the cylinder valve closed, except when using the. When finished welding: a) Close the cylinder valve to stop gas flow. b) Depress the gun trigger briefly to release the pressure in the gas hose. c) Turn off the. Making A Weld 1. See Recommended Processes And Equipment section for selection of welding wire and shielding gas and for range of metal thicknesses that can be welded. 2. See the Application Chart on the inside of wire feed section door for information on setting the controls. 4. Check that the polarity is correct for the welding wire being used and that the gas supply, if required, is turned on. 5. When using Innershield electrode, remove the gas nozzle and install the gasless nozzle. This will improve visibility of the arc and protect the gas diffuser from weld spatter. Refer to the MAINTE- NANCE section for details on nozzle replacement. 6. Refer to Figure B.7. Connect work clamp to metal to be welded. Work clamp must make good electrical contact to the workpiece. The workpiece must also be grounded as stated in Arc Welding Safety Precautions in the beginning of this manual. 7. Position gun over joint. End of wire may be lightly touching the work. 8. Lower welding helmet, close gun trigger, and begin welding. Hold the gun so the contact tip to work distance is about 3/8 inch (10 mm). FIGURE B.7 GUN CABLE 3.

19 B-6 OPERATION B-6 9. To stop welding, release the gun trigger and then pull the gun away from the work after the arc goes out. 10. When no more welding is to be done, close valve on gas cylinder (if used), momentarily operate gun trigger to release gas pressure, and turn off the. Cleaning Tip And Nozzle Clean the contact tip and nozzle to avoid arc bridging between the nozzle and contact tip which can result in a shorted nozzle, poor welds and an overheated gun. Hint: Anti-stick spray or gel, available from a welding supplier, may reduce buildup and aid in spatter removal. PROCESS GUIDELINES The can be used for welding mild steel using the GMAW, single pass, process which requires a supply of shielding gas or it can be used for the self shielded, Innershield process (FCAW). The recommended gases and electrodes for GMAW are welding grade CO 2 gas or an argon-co 2 blended gas (75 to 80% argon and 25 to 20% CO 2 ) and.025" (0.6 mm) diameter Lincoln Super Arc L-56 mild-steel welding wire. The recommended electrode for the self-shielded process is (0,9 mm) diameter Lincoln Innershield NR-211-MP. This electrode can be used for all position welding of 20 gauge through 5/16 (1,0 8,0 mm) thick steel [multiple passes are required for 1/4 and 5/16 (6,0 and 8,0 mm)]. WARNING Use of the GMAW process with the on thicker materials than recommended may result in poor welds. The welds may look good, but may just be sitting on top of the plate. This is called cold casting and will result in weld failure The is suitable for.035" Aluminum wire and.030" stainless wire. Refer to Table B.1 for Recommended Procedure Settings. Aluminum wire requires K663-2 Aluminum Welding kit. See ACCES- SORIES section. It is important when changing between welding with steel wire and aluminum to exchange feeding components due to the lubricant applied to steel wire. Failure to do so may result in contaminated welds when welding aluminum TABLE B.1 Welding Procedures NR-Not Recommended CAUTION Shielding Voltage/Wire Speed Process Welding Wire Gas 22 ga 16 ga 12 ga 1/8 3/16 1/4.035 Dia(0.9mm 100% Argon C-5 E-8.5 H-10 J-109 NR NR 4043 Aluminum Wire MIG DC+ 16 ga 14 ga 12 ga 10 ga.030 Dia 98% Argon/ A-3 C-6 D-7.5 D L Stainless 2% Oxygen Steel Wire CHANGING MACHINE OVER TO FEED OTHER WIRE SIZES The is shipped from the factory ready to feed (0,6 mm) diameter wire. To operate the with other sizes of wire, it is necessary to change the contact tip and change the drive roll over to other sizes. Refer to Changing the Contact Tip and Changing the Drive Roll, in the MAINTE- NANCE section, for specific information on these procedures. WELDING WITH FCAW (Innershield) Welding with Innershield requires an Innershield Welding Kit. A gasless nozzle is provided in the Innershield Welding Kit. When using Innershield electrode, installing the gasless nozzle will improve visibility of the arc and protect the gas diffuser from weld spatter. Additionally included is a gun cable liner to permit proper feeding of.035 (0,9 mm) Innershield wire. Refer to the ACCESSORIES section for details on obtaining this kit.

20 B-7 OPERATION B-7 OVERLOAD PROTECTION Output Overload The is equipped with a circuit breaker which protects the machine from potential damage from excessive output current. The circuit breaker button will extend out when tripped. The circuit breaker must be manually reset. Thermal Protection The duty cycle is exceeded a thermostat will shut off the output until the machine cools to a normal operating temperature. This is an automatic function and is self resetting. Wire Feed Overload Protection If the has an automatic electronic protection circuit to protect the wire feed motor. If excessive motor overload occurs (due to excessive feeding force, jammed drive rolls, or shorted motor leads) the circuit will shut down the wire feed motor and the welding power output. The wire feed shut-down circuit will reset automatically when the gun trigger is released. However shut-down will reoccur if the overload situation is not corrected.
